The domestic baking oven of the coating machine is generally supported by support rods at present, and the interval between two support rods is about 0.3-0.5 meter. The number of required support rods increases along with increase in the length of the baking oven of the coating machine, the friction of the support rods to the matrix (aluminum foil or copper foil) correspondingly increases, and the matrix (aluminum foil or copper foil) can easily produce scars, creases and other defects, thereby seriously affecting the product quality. In the key technical scheme to solve the problems, the baking oven device of the matrix (aluminum foil or copper foil) suspension type coating machine comprises a baking oven body (with an outer baking oven shell, an inner baking oven core, a baking oven door and a baking oven rack), a ship-shaped independent air intake chamber, an improved air nozzle, a drying chamber, an exhaust chamber, a circulating air chamber, a circulating air duct, an air blower, a heating device and the like, and is characterized in that wind force in the baking oven of the coating machine is used for supporting the matrix, so that the matrix is in a suspended state in the baking oven. Due to the matrix suspension type structure, the invention solves the problem of friction of the support rods to the matrix in the baking oven of the coating machine, and facilitates the improvement of the quality of the coated product, the increase of the length of the baking oven so as to speed up the coating, the enhancement of the production efficiency and the like.
Description
Technical field
The present invention relates to a kind of lithium ion battery coating machine, especially a kind of matrix (Copper Foil or aluminium foil) suspension type coating machine bake oven device.
Background technology
Coating is a requisite operation in the lithium ion battery production process, also is the critical process that directly influences every performances such as battery security, capacity, uniformity.
Coating exactly with the pasty state viscous paste of making, uniformly, continuously or being coated on the matrix (aluminium foil or Copper Foil) of being interrupted, guarantees the consistency of thickness of each coating position and coating thickness is controlled in the margin of tolerance of technological requirement.And coating machine oven is one of parts of coating machine, is a kind of device that will be coated in the slurry oven dry on the matrix.
Common coating machine oven is divided into oven main body (comprising the inside and outside courage of baking oven, oven door, baking oven frame etc.), inlet air plenum, tuyere, product drying chamber, circulation air path, air blast, heater etc.Be interconnected between inlet air plenum and the tuyere and with airtight mutually between the product drying chamber, dry hot blast blows out through tuyere from inlet air plenum, enter the product drying chamber, part wind can be discharged through exhaust outlet, and all the other hot blasts are got back to inlet air plenum through circulation air path through air blast and heater.
Coating machine oven length is generally longer, is generally 12 meters～21 meters, and the coating speed of coating machine is fast more, and the baking oven of its requirement is also long more.Be coated with the matrix (aluminium foil or Copper Foil) that enters oven interior and dry, needed dynamics to support, made it be unlikely to tenesmus in coating machine oven inside.At present domestic coating machine oven generally adopts support bar to support, and promptly in coating machine oven inside support bar is set, and the interval between two support bars is about 0.3 meter～0.5 meter.Therefore, the length of coating machine oven is long more, and its needed support bar is also many more, and support bar is also big more to the frictional force that matrix (aluminium foil or Copper Foil) is produced, when this frictional force was big, matrix (aluminium foil or Copper Foil) was easy to generate defectives such as scar, wrinkle, has a strong impact on product quality.
As can be seen from Figure 1, 2, 3, common coating machine oven supports matrix (Copper Foil or aluminium foil) by support bar, in the actual moving process, support bar can produce frictional force to matrix (Copper Foil or aluminium foil), and, the length of baking oven is many more, and support bar is corresponding also many more, and support bar is also big more to the frictional force that matrix (Copper Foil or aluminium foil) is produced.
Summary of the invention
Development purpose of the present invention is to overcome the defective that prior art exists, and provide the friction problem of a kind of solution coating machine oven inner bracing piece to matrix (aluminium foil or Copper Foil), improve the product quality of coating, increase baking oven length, improve coating machine efficient to accelerate coating speed.
Matrix of the present invention (aluminium foil or Copper Foil) suspension type coating machine bake oven device, comprise oven main body (the inside and outside courage of baking oven, oven door, baking oven frame), ship type independent air intake chamber, modified tuyere, drying chamber, wind chamber, circulation air compartment, circulation air path, air blast, heater etc., it is characterized in that: adopt the wind-force of coating machine oven inside to come support substrate (aluminium foil or Copper Foil), make matrix (aluminium foil or Copper Foil) in baking oven, be in suspended state.
Described ship type independent air intake chamber owing to adopt the design of ship type, can guarantee that the blast of each position in the inlet air plenum is roughly the same, and then guarantees that the wind-force wind speed that each tuyere blows out is all roughly the same.
Described modified tuyere, the size that not only can regulate the air port, and its wind concentration that blows out can produce enough support forces matrix (Copper Foil or aluminium foil) is suspended.
Beneficial effect of the present invention is: adopt the wind-force of coating machine oven inside to come support substrate (aluminium foil or Copper Foil), make matrix (aluminium foil or Copper Foil) in baking oven, be in suspended state, solved the friction problem of coating machine oven inner bracing piece to matrix (aluminium foil or Copper Foil), help improving the product quality of coating, increase baking oven length to accelerate coating speed, enhance productivity.
